以二矽酸鋰全瓷鑲嵌體復形右下第一大臼齒之病例報告

Restoring A Lower Right First Molar with a Lithium Disilicate Onlay: A Case Report

大範圍蛀牙造成的牙齒缺損早期多建議病患製作牙冠或金屬鑲嵌體。隨著現代牙科黏著劑的進步,陶瓷嵌體已成為大範圍齲齒的治療選擇 / 復形物之一,不但兼 具美觀,也能較保守的修磨牙齒。然而陶瓷鑲嵌體挑戰傳統補綴觀念的設計,今日仍是百家爭鳴,不管是在材料的選擇、修形原則、黏著方式等都是臨床醫師激盪新 想法的領域。 本病例為一位中年女性,經咬翼片檢查發現右下第一大臼齒近心及遠心繼發性齲齒,移除蛀牙後,於橡皮防濕裝置下進行鑲嵌體的修形,印模後,選擇 二矽酸鋰材質製作全瓷鑲嵌體復形右下第一大臼齒。內文涵蓋臨床治療步驟及口內照片、治療前後 X 光片的變化,最後做討論與總結。

 

In the early days, popular treatments of large tooth defects were crowns or metal inlay/onlays. With the development of modern dental adhesives, ceramic inlay/onlays have become alternative treatment options. Ceramic inlay/onlays have the advantages of esthetic appearance and preserving more tooth structure. However, the design of ceramic inlay/onlays challenges traditional prosthodontic concepts. There are still no final conclusions when it comes to material selec- tion, preparation principles, adhesion methods, etc. This case was a middle-aged woman who came to our out patient department for a full mouth caries check-up. After radiographic examination, secondary caries over the lower right secondary molar were founded. After evaluation and discussion, we chose lithium disilicate onlay as the treatment plan for the tooth. This article includes the clinical treat-ment steps, intraoral photos, x-ray films before and after treatment, final discus- sion and a summary.
